LUBRICATING DEVICE. i

Specication of Letters Patent.

Application tiled .Tune 21, 1811. Serial No. 634,415.

To all' 'whom it may concern:

. a citizen of the United States, and a resident of Claremont, county of Sullivan, State of New Hampshire, (whose post-office address is Claremont, New Hampshire,) have invented an Improvement in Lubricating Devices, of which the following description, in connectionwith the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention consists of improvements in lubricating devices particularly adapted for use in connection with lubricating devices for engines.

The invention will be best understood by reference to the following description when taken in connect-ion with the accompanying illustration of one specific embodiment thereof, While its scope will be more'particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of the crank chamber and associated parts of an engine equipped with one form of the invention. Fig. 2 is a sectional elevation taken through the crank chamber. Fig. 3 is an end elevation of the crank chamber showing the oil receiving tank and the distributing pipes. Fig. 4 1s a section through the oil-receiving tank. Fig. 5 is a section showing the oil intercepter and delector and l its relation to the crank disk; and Fig. 6

shows a detail of the lubricant supply pipe.

Referring to\ the drawings and to the illustrative embodiment of the invention therein shown, at l there is represented a portion of the bed plate or frame work of a steam compressing engine having the crank disk 2 and connecting rod 3. The crank chamber is in the form of a well adapted to contain a supplyT of oil or other lubricant 4 in which the rotatable crank disk is partly immersed. A supply of oil is maintained in the crank chamber shown, and also in an adjacent chamber 5 for the valve eccentrics, equalization of the oil in the two chambers being provided for by the connecting pipe 6 provided with the gage glass 7.

In the disclosed form of engine, the ac- -tion of the crank disk in the oil 4: is relied u on to distribute oil to the various parts oiithe engine which are required to be contion as to take full advantage of the stantly lubricated, While the machine-is' in operation, such as the cross head 8, the bearing box 9 and the valve eccentrics in the chamber 5. Heretoore it has been proposed to distribute oil to these various parts by scraplng it from the Vcrank diskas the latter rotates and allowing the oil thus scraped or intercepted to iow by gravity alone to lubricating devices arranged at a lower level. It has also been proposed to lubricate certain parts by utilizing the cur- Patentea Mar. 5,1912.

rent'or iow of oil contained in the bottom of the crank chamber as it is agitated by the rotation of the crank disk to drive a portion of the lubricant into a collector arranged in the body of oil and lift it to the lubricating devices, the latter located at a higher level.

The present invent-ion presents a marked improvement over both the described arrangements, the oil being intercepted and removed from the diskbut at such a osii h velocity attained by such portion of the tgiil as clings to the disk in its rapid movement, When intercepted it is deflected by a suitable deflecting wall so that its dynamic head is utilized under the most favorable circumstances and it is caused to force the oil in advance of it into a suitable receiver arranged at a higher level from which it can be distributed by gravity to any required part of the machine.

Referring to the drawings, the intercepting and deflecting member is shown in Figs. l, 2 and .5 and comprises a slightly flared receiver 10 held fixed in close operative relation to the face of the disk and preferably, though not necessarily, in contact therewith as represented in Fig. 5. In Fig. 5 the lower lip 11 of the Vdeflector is shown as resting against the face of the crank disk, so that the oil which is carried over by the crank disk and by the time it reaches the deflector has acquired a high velocity, is intercepted and driven into the open mouth of the receiver. The top of the intercepter is closed by the delecting wall 12 so that the oil which is driven into the same is deiiected downwardly and forced into the sup ly pi e 13 which connects with the rear end o f tiie receiver.

The supply pipe passes out -through the casing and into the lower end of a suitable receiving tank. The latter consists of an inner casing 14 and an outer caslng 15, the

pipe 13 connecting with the interior of the inner casing. The inner casing 14 supports a perforated sheet metal cylinder 16 to the interior of which the oil is delivered and also an outer perforated sheet metal cylinder 17, the two perforated cylinders being separated by a body of straining material 18, such as curled hair, through which communication between the inner oil-receiving cylinder the interior of the outer casing is had so that the oil is filtered in passing therethrough. The oil is retained Within the outer casing acting as a vholder or reservoir and distributed therefrom through distribut-ing pipes which may be of any suitable number and having any suitable'location according to the number and position. 'of the parts to be lubricated. Pieces of Wire 19 and 2O arranged at right angles are inserted through the upper parts of the perforated sheet met-al cylinders so as to maintain the same central Within the outer casing 15. 'lhe sheet metal cylinders are S01-, dered or otherwise secured to the inner'casing 14 and the latter is removablefrom the outer casing so that lby removing the top 21 of the tank, the cylinders and lnner casing can be removed as a unit and the straining material cleaned. A

The` intercepteris applied to the crank disk onthe upper side thereof and preferably at or about the position shown. This.

position may be varied more or less according to the normal ,speed velocity of the crank disk, but at approximately the position shown the oil can not only be more` readily and effectively intercepted but acquires its greatestvelocity so that t-he apparatus is most effective in utilizing the dy' namic head of the oil. With the' ap aratus operated at normal speed, the disk-a hering oil, Which is intercepted and driven in a substantially tangential direction into the receiver, will pass down the supply pipe 13 and up into the receiver 15, maintaining a head substantially as shown in Fig. 2 under Which it may be distributed to the various parts to be lubricated. The employment of a `receiver equalizes the head under slight variationsof speed or cessations of supply due to any other cause. The utilization of the dynamic head of the oil-l taken from the upper side of the crank disk, particularly in conjunction with the receiver, renalso lubricating conduit 26 for the chamber'rl' (1 1 i 1e sup i e 13 wiere it passes through thisJ brasihg as shown in Fi 6 is provided with a spring pressed was er 27 which prevents the 'exit of -oil from the casing which may be spattered thereagainst by the action of the crank disk. A While .I have herein shown and described for purposes of illustration one specific form` of the invention, lit is t be understood that the same is not limited to the details 0f constructionv herein shown nor to the specfic arrangement of parts, but that extensiveA deviations may be madetherefrom without departing from the spirit of the invention. i
